No way… am I psychic again?
It could be considered a weaker situational irony, simply because it it unexpected that I would comment a proposed title. It is the disparity of intention and result… when the ending result is contrary to the desired intention or expected effect.

Sort of. It’s still not irony. Although coincidence and irony are similar, this is still really just coincidence. Situational irony is difficult to describe, but it could be explained as a situation where the percieved reality is in stark contrast with the “actual” reality or when intention is in stark contrast with the result. The fact that your comment was a possible title isn’t contrasting or opposing an expectation; it just wasn’t expected is all. See the difference? It would’ve been ironic if you’d said “Hey, you know what would’ve been a good title for this page? “Jealous Much?””, because then the reality that it was in fact a possible title at one point would’ve been in contrast with your expectations.
